Connecting the systems that power commerce

Designing and implementing integration flows between Heads' commerce platform and enterprise retail systems. I map data flows between POS, ERP, order management, and payment services — handling API configuration, webhook routing, and troubleshooting data sync issues across multi-store environments. Responsible for technical onboarding of new enterprise clients, ensuring their existing systems connect cleanly to our REST APIs.

Built a POS reselling business from scratch — sourcing, configuring, and deploying point-of-sale systems with payment terminal integrations. Handled end-to-end setup including fiscal compliance (Swedish tax authority integration), payment acquiring connections, and hardware-to-software configuration. Reached 700k SEK revenue before joining Heads.

Configured merchant accounts and integrated payment terminals with Northmill's acquiring platform. Managed the technical pipeline from terminal provisioning through payment gateway connection to transaction reconciliation. Handled B2B billing flows and debugged integration failures between POS hardware and the bank's processing APIs.

Owned enterprise integration and deployment for accounts including IKEA and AXS. Managed device fleet provisioning via Apple Business Manager (MDM), configured POS-to-backend data flows, and acted as the technical bridge between enterprise clients and engineering — translating integration requirements into actionable specs. Deployed and maintained hundreds of iPads across multi-location retail environments.

Built PowerShell automation for log collection, backup verification, and system health monitoring across distributed POS environments. Diagnosed integration failures between POS software, SQL databases, and peripheral hardware via remote sessions. Developed repeatable troubleshooting procedures that reduced escalation time.
